I think it just depends on where you live. I contacted my sewage an water board about the choramine in our water supply and while I don’t recall the exact number off of the top of my head, it’s high. Very high. That is because of our water source (the very bottom of the very dirty Mississippi River) and our near constant high temperatures is a breeding ground for harmful bacteria. Other areas may not have this issue, you lucky dogs... They also stated that it is a stable chemical that does not break down, unlike chlorine. Every one of my orchids that I had at the time when I was using tap had burned roots. Switching to r/o water for my sensitive ones and using a neutralizer for the rest that get tap has helped immensely
